a sustained-release tablet formulation should ideally have a proper release profile insensitive to moderate changes in tablet hardness that is usually encountered in manufacturing. in this study, matrix aspirin (acetylsalicylic acid) tablets with ethylcellulose (ec), eudragit rs100 (rs), and eudragit s100 (s) were prepared by direct compression. the release behaviors were then studied in two co...

the present study involves preparation and evaluation of gastric-mucoadhesive microparticles with metformin hydrochloride as model drug for prolongation of gastric residence time. the microparticles were prepared by the emulsification solvent evaporation technique using polymers of carbomer 934p (c) and ethylcellulose (ec). the microparticles were prepared by emulsion solvent evaporation method...

objective(s): this study evaluates the effect of substitution of microcrystalline cellulose (mcc) with ethylcellulose (ec) on mechanical and release characteristics of theophylline pellets. materials and methods: the effect of addition of ec was investigated on characteristics of pellets with varying drug content prepared by extrusion-spheronization. also the effect of type of granulating liqui...
